IMPROVEMENT IN AXLE-BOXES FOR VEHICLES.

Specification forming part of Letters Patent No. 10,100, datedSeptembcr 29, 1863.

To all whmn it may concern:

Be it known that I, SAMUEL F. GREEN, of Oroton Falls, in the county of VVestchester and State of New York, have invented a new and useful Improvementin Boxes for the Axles of Vehicles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is alongitudinal central section of my invention, taken in the line mac, Fig. 2, the axle not being bisected Fig. 2, an external view of the same applied to an axle; Fig. 3, a transverse section of the same, taken in the line y 3 Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents an axle for a vehicle, which may be constructed in the usual way with a screw, a, cut on its outer end to receive a nut, B. r

O is a collar at the inner end of the axle A, against which the inner end of the box and hub bear. These parts, being of usual construction, do not require a minute description.

D represents the box, which is constructed of cast-iron, and in two equal longitudinal parts, a a, one of said parts having recesses b I) in it to receive lugs or projections c c on the other part, as shown clearly in Fig. 3. These recesses and lugs extend from the inner end of the box to a point nearly midway of the box, and each box has a longitudinal wing, d, cast on it, said wings extending from the inner end of the box toward its front end nearly half its length. (See Fig. 2.) On the front or outer ends of the two parts a a of the box there is cut a screw, 6, to receive a nut, E, which has a circular plate or flange, f, projecting from its outer end at right angles. The two parts a a of the box D are lined with Babbitt metal, g. This metal may be secured to the parts tr a of the box D by screws or rivets h. t

The nut E and its plate or flangeffit in a recess cut in the outer end of the hub, which is shown in red outline in Fig. 1. This nut E secures the outer ends of the two parts a a of the box D in close contact, and it also serves asa means to draw the box snugly into the hub, a short space being allowed between the end of the box and the outer part of the nut, to admit of the latter being screwed up when necessary to etfect this result. The wings d d fit in recesses made in the hub to receive them, and prevent the hub from turning on the box. The plate or flangefot' the nut serves as a bearing for the box D, preventing the latter from working loose in the hub in a lateral direction-that is to say, in a direction at right angles to its axisa contingency of frequent occurrence with ordinary boxes, as they are not provided with any bear ing whatever at their outer ends. This nut,

therefore, it will be seen, is an important feature of the invention.

The hub is retained on the axle by the nut B, which is screwed up against the plate or flange f, or against a washer interposed between them.

The forming of the box D in two parts admits ot' the same being lined with Babbitt metal in a proper manner. A box cast in one piece cannot be thus lined. Many attempts have been made to accomplish this result by casting; but the metal shrinks, in cooling, to such an extent as to leave the lining loose in the box. In case the lining 9 should become worn by use, it may be very readily removed and replaced by a new one.

I do not claim, broadly, the constructing of an axle-box in two longitudinal parts, irrespective of the screw, nut, and plate, as herein described; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with the two parts of the divided box D, axle A, and nut B, of the nut E, in the manner and for the purpose herein shown and described.

SAMUEL F. GREEN.
